Are you sure JBII's fuel doesn't burn cleaner than refinery fuel?

I would think it does actually, hence reducing greenhouse emissions.

For example, their fuel is lower in sulfur than normal fuel oil #6.

Not sure why you are ranting about John being stupid for suggesting low sulfur fuel has less emissions than high sulfur fuel.  The EPA seems to agree with John, not you:
